Just a starter server that I've seen myself writing several times now

basic-server.js

const path = require('path')
const express = require('express')
const morgan = require('morgan')

const app = express()

app.set('x-powered-by', false)
app.set('view engine', 'ejs')
app.set('views', path.resolve(__dirname, '..', 'views'))

app.use('/assets', express.static(path.resolve(__dirname, '..', 'build')))
app.use(morgan('tiny'))

app.get('/', (req, res) => res.render('index'))

app.listen(8000, () => console.log('Listening on :8000'))
